WEMSSEMBLING APPARATUS FOR PRINTING PRESSES AND THE Application filed.June 2,

My invention relates to printing presses, and more particularly tofolding and web defleeting and guiding mechanism used as an appurtenancethereto, and to an improved method of guiding the webs of paper passingthrough such printing presses, and has for one of its principal objectsto provide mecha: nism by which a comparatively wide web of paper, or aplurality of such'webs placed one upon the other, may be cut or slitinto narrower strips and said strips distributed in various ways as itmay be desired, and assembled with other strips and cut and folded, in asimple and efiicient manner, as will be hereinafter described. Otherobjects of the invention will appear from the following description.

The invention consists in the novel arrangement and combination ofvarious devices, elements and parts, as set forth in the claims hereof,certain embodiments of the same being illustrated in the accompanyingdrawings and described in this specification.

In the accompanying drawings,

Fig. 1 is a diagrammatic view of a folding mechanism showing oneembodiment of my invention; and

Fig. 2 is a similar view showing a modification of the same.

In carrying my invention into efiectin the particular embodiment thereofwhich is shown in Fig. 1 of the accompanying draw ings, I provideformers 11, 11, of the usual or any suitable construction, over whichone or more webs of paper maybe passed. In the drawings the formers areshown covered by paper which is passing over the sa.me, the paper beingdesignated 50. Ad acent the upper part of these formers 1s a rod 12 uponwhich'are swingingly mounted a series of rotating knives. or cutters 13,which are adapted to out the webs passing over said formers intonarrower strips, in a manner which will be well understood from anexaminat-ion of the drawings. In Fig. 1 of the drawings a series ofthree wide webs are shown passing over the duplex former, with threecutting knives in operation which sever these wide webs longitudinallyinto four narrower series of webs, which then proceed down over theformers in the usual manner. Assuming that as shown in Fig. 1 there arethree layers or webs of paper passing over the duplex former, it willbeseen. that these 1926. Serial .No. 113,199.

. and that these can be disposed oi invarlous ways, by threading thedifi'erent layers in different combinations through the various rollers.For instance, the three layers or webs of paper which pass over the lefthand half of the duplex former in Fig. 1, will be folded and passedthrough between the rollers 14 as a six-ply web. From that point itwould be possible to pass the whole series of'six webs down between therollers 16. 17 and 18 (the said series of webs being at this pointdesignated by the reference numeral 54) and then downthrough the cuttingcylinders 22 and 23 where the webs are cut into suitable lengths, foldedbetween the rollers 26 by a suitable tucking blade, delivered into thefly delivery 28 and from there to the delivery belt 30, all in a mannerwhich will be well understood. Or if desired, two webs may be deflectedto the right after passing between the rollers 16and pass over theroller 32, two more may be deflected after passing between the rollers17 and pass over the roller 33, and the remaining two may be deflectedafter passing between the rollers 18 and pass over the roller 34, allthese six being then col lected together and assembled with thecomplementary webs which have passed down from the right hand half ofthe duplex former, between the rollers 15, 19, 20 and 21, the wholeseries of 12 narrow webs then passing between the cutting cylinders24cand 25, folding rollers 27, and into the fly delivery 29 and to thedelivery belt 31.

It will be seen that many different combinations may be made and thevarious webs or layers of associated Webs may be sorted out andassembled in different ways as desired, and that when desired it may beprovided whenever necessary that but a small number of layers of paperwill pass over any one roller at any considerable angle, so as to avoidthe creeping, buckling and wrinkling of the layers one upon anotherwhich would otherwise result.

In the modification of the invention shown in Fig. 2 I show formers 11and knives 13 mounted on a rod 12, as in Fig. 1. I also show rollers 40and 41 on one side and rollers 42 and 43 on the other side. But in thisform .of the invention I provide additional pairs of rollers 44 and 45,as will be seen in the middle portion of Fig. 2. The remainder of themechanism in Fig. 2 is substantially the same as in Fig. 1.

It will be seen that by the modified arrangement of parts shown in Fig.2, it is possible to accomplish somewhat different results from thosedescribed, in assembling the sheets, which it unnecessary to describe indetail, as the same will be obvious.

The operation of the invention has been already sufiiciently describedin what has been said above with regard to its construction,

and the advantages have been to some extentpointed out, and indeed areobvious from an examination of the drawings. I might, however, callattention to the fact that the form of invention shown in Fig. 2 isparticularly well adapted to cases where vertical space is limited and asomewhat compressed form of construction is. required, while the formshown in Fig. 1 is better adapted to handling a large number ofsuperimposed webs or layers of paper without slipping, wrinkling orbuckling.

Having thus described my invention, what I claim as new and desire tosecure by Let ters Patent is as follows: I

1. In a web assembling apparatus for printing presses and the like. thefollowing elements in combination: a former over which a plurality ofwebs of paper may pass, means for feeding said webs of paper, aplurality of cutting cylinders for said webs, and meansintermediate saidformer and said cutting cylinders adapted to separate said webs andseparately direct the same with reference to said cutting cylinders.

2 In a web assembling apparatus for prlnt- 'ing presses and the like.the following elements in combination: a former over which a pluralityof webs of paper may pass, means for feeding said webs of paper, a pairof cutting cylinders for said webs, and means intermediate said iormerand said cutting cylin der-s adapted to receive the webs from a portionof said former, separate the same and separately direct the same withreference to a web from another portion of said former and withreference to said cutting cylinders, said means comprising a pluralityof pa rs of rollers adjacent said former and at varying dis t-ancestherefrom, one pair of said rollers being adapted to pass certain ofsaid webs of paper therebet'ween and to permit one of said webs to bedeflected laterally therefrom after passing therethrough, a succeedingpair of said rollers being adapted to pass certain of said webs ofpaper, not including the web previously deflected, therebetween and topermit one of said webs after passing therethroughto be deflectedlaterally therefrom, and a plurality of rollers located laterally ofsaid pairs of rollers, adapted to receive said deflected webs of paperrespectively and direct the same with reference to a web from anotherpart of said former and with reference to said cutting cylinders.

' 3. In a web assembling apparatus for printing presses and the like,the following elements in combination: a former over which a pluralityof webs of paper may pass, means for feeding said webs of paper, a pairof cutting cylinders for said webs, located out of the normal line oftravel of said webs, and means intermediate said former and said cuttingcylinders adapted to separate said webs and separately direct the samewith reference to said cutting cylinders.

4:. The method of deflecting a group of webs of paper out of a straightline and into a new direction at a substantial angle to their then path,without wrinkling or buckling, which consist-s in dissociating saidwebs, leading same separately toward a pair of cutting cylinders,associating said webs and subjectilng same to the action of said cuttingcylin- BPS.

In witness whereof I have hereunto signed my name this 25th day of May.1926.
